Hybris 自定义电子邮件设置自定义属性

Question

我正在创建一个自定义电子邮件，应在填写预约表格后发送给客户。我需要额外的属性，所以我扩展了AbstractEmailContext：

public class AppointmentEmailContext extends AbstractEmailContext

{

   private String myAttribute;

   ...

}

在我开始这个过程之前，我正在我的 EventListener 中设置属性：

final AppointmentProcessModel storeFrontCustomerProcessModel = (AppointmentProcessModel) getBusinessProcessService()

                .createProcess(

                        "appointmentEmailProcess-" + event.getEmail() + "-" + System.currentTimeMillis(),

                        "appointmentEmailProcess");

storeFrontCustomerProcessModel.setMyAttribute("[e-mail]");

getModelService().save(storeFrontCustomerProcessModel);

getBusinessProcessService().startProcess(storeFrontCustomerProcessModel);

在我无法获取这些参数的init方法中，AppointmentEmailContext我可以正确设置它们并将它们传递给电子邮件模板。另一件事是，在init方法中输入的 ProcessModel不是 的实例AppointmentProcessModel，而是 的实例StoreFrontCustomerProcessModel，即使我AppointmentProcessModel正在扩展它。

我也尝试添加AppointmentProcessModel这样的：

public class AppointmentEmailContext extends AbstractEmailContext<AppointmentProcessModel>

{

...

}

并使用正确的参数调整 init 方法（+ 添加覆盖方法），但随后在创建过程时出现错误：

ERROR [hybrisHTTP21] [HybrisApplicationEventMulticaster] java.lang.InstantiationException: mypackage.core.appointment.model.AppointmentProcessModel

 java.lang.RuntimeException: java.lang.InstantiationException: mypackage.core.appointment.model.AppointmentProcessModel

我不知道保留这些属性是否有问题，或者我是否应该以其他方式传递这些属性。

更新：我试图添加AppointmentProcess到*-items.xml文件，我做系统更新，但没有改变。我在后台检查了该类型已添加并且它是从StoreFrontCustomerProcess. 定义如下：

        <itemtype code="AppointmentProcess" extends="StoreFrontCustomerProcess"

                  autocreate="true" generate="true"

                  jaloclass="mypackage.jalo.AppointmentProcess">

            <attributes>

                <attribute qualifier="email" type="java.lang.String">

                    <persistence type="property" />

                </attribute>

            </attributes>

        </itemtype>

通过 HMC 交叉验证，您的属性是否保存在 storeFrontCustomerProcessModel 中？尝试更改AppointmentEmailContext类，如public class AppointmentEmailContext extends AbstractEmailContext<AppointmentProcessModel>{&nbsp; &nbsp;private String myAttribute;&nbsp; &nbsp; @Override&nbsp; &nbsp; public void init(final AppointmentProcessModel appointmentProcessModel, final EmailPageModel emailPageModel)&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; super.init(appointmentProcessModel, emailPageModel);&nbsp; &nbsp; &nbsp; &nbsp; myAttribute = appointmentProcessModel.getMyAttribute();&nbsp; &nbsp; }&nbsp; &nbsp; public String getMyAttribute() {&nbsp; &nbsp; &nbsp; &nbsp; return myAttribute;&nbsp; &nbsp; }&nbsp; &nbsp; //...}编辑用户尚未创建 Item 类型AppointmentProcess，后来他创建了它，正如我在评论中提到的，问题已解决！！
